29607839 ÷ 831 
The aim is to understand the frequency of 831 in 29607839.

On to step 1:
When dividing 2 by 831, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 831

Let's proceed to step 2:
831 goes into 29 0 times with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 831

On to step 3:
296 divided by 831 is 0 with a remainder of 296.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 296 leaves us with 296.
Bring next digit (0) of the dividend behind the 296 and repeat the process: 2960 / 831

Advancing to step 4:
When dividing 2960 by 831, we get 3 with a remainder of 467.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 467 after subtracting 2493 from 2960.
Bring next digit (7) of the dividend behind the 467 and repeat the process: 4677 / 831

Moving on to step 5:
If we divide 4677 by 831, we get 5 and a remainder of 522.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 4155 from 4677 to get 522.
Take the next digit (8) from the dividend and append it to 522, then repeat: 5228 / 831

Step 6:
831 can be fit into 5228 6 times, resulting in a remainder of 242.
Write down 6 as next digit of the result. 
Result so far: 356.0
If we subtract 4986 from 5228, we get 242.
Take the next digit (3) from the dividend and append it to 242, then repeat: 2423 / 831

Advancing to step 7:
831 can be fit into 2423 2 times, resulting in a remainder of 761.
Use 2 as the next digit of our solution. 
Result so far: 3562.0
If we take 1662 away from 2423, we end up with 761.
Append the next digit (9) from the dividend to 761 and continue with: 7619 / 831

Advancing to step 8:
831 can be fit into 7619 9 times, resulting in a remainder of 140.
Put 9 as the next digit of the answer. 
Result so far: 35629.0
Subtracting 7479 from 7619 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 9:
831 can be fit into 1400 1 times, resulting in a remainder of 569.
The next digit of our result is 1. 
Result so far: 35629.1
Subtract 831 from 1400 to get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Advancing to step 10:
831 goes into 5690 6 times with a remainder of 704.
Put 6 as the next digit of the answer. 
Result so far: 35629.16
Subtract 4986 from 5690 to get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Step 11:
When dividing 7040 by 831, we get 8 with a remainder of 392.
Write down 8 as next digit of the result. 
Result so far: 35629.168
If we take 6648 away from 7040, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 12:
831 goes into 3920 4 times with a remainder of 596.
Put 4 as the next digit of the answer. 
Result so far: 35629.1684
Subtracting 3324 from 3920 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 13:
831 goes into 5960 7 times with a remainder of 143.
Record the quotient 7 as the next digit in the result. 
Result so far: 35629.16847
If we subtract 5817 from 5960, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 14:
1430 divided by 831 is 1 with a remainder of 599.
Write down 1 as next digit of the result. 
Result so far: 35629.168471
Subtracting 831 from 1430 leaves us with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

On to step 15:
831 can be fit into 5990 7 times, resulting in a remainder of 173.
Record the quotient 7 as the next digit in the result. 
Result so far: 35629.1684717
If we take 5817 away from 5990, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 16:
The number 831 fits into 1730 2 times, leaving a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 35629.16847172
Deduct 1662 from 1730 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 35629.16847172 and a remainder of 6.8e-08.
